The Main Causes of Air Duct Contamination

The HVAC ducts are internal components of the system and the air which they transfer passes through special filters. How come they can get contaminated then? There are various ways in which this can happen. Let’s take a look at them so that you know when air duct cleaning will be required.

What Could Go Wrong and How to Deal with the Problem

Unfortunately, the air filters can fail you for various reasons. The list includes irregular air filter cleaning and replacement. It is also possible for the filters to be of poor quality and to work much less effectively than you would expect them to. In such situations, they cannot filter all the dust and pollen which the circulated indoor air carries. Some of it remains inside the ducts and ever greater amounts get accumulated over time.

Leaks in the ductwork are also not uncommon. They can be caused by improper installation and different kinds of damage. The holes, which could be quite small, let external air in. It usually carries great amounts of dust and sometimes dirt. The result is faster growth of the accumulations. In this case, the solution will involve air duct repair in addition to cleaning.

If water gets into the HVAC ducts through the holes, the risk of mold growth increases considerably. This is also the case when the ductwork is poorly insulated or the insulation gets damaged. Mold removal requires the use of special cleaning techniques. Various methods can be used for preventing future contamination with mold. The list includes advanced approaches such as the setup of UV cleansers which produce ultraviolet light killing the spores.

You should deal with HVAC air duct problems timely to prevent greater trouble.
